Understanding Deflate

Copy Link

Deflate compression is used to compress data, demonstrated with the string 'TOBEORNOTTOBEORTOBEORNOT'.
GZIP adds a wrapper around the compressed data, which includes metadata like compression method, flags, and timestamps.
The DEFLATE format uses Huffman coding and LZ77 tokens to represent data, including literal characters and copy commands.
Copy commands in DEFLATE include Huffman codes, extra length bits, distance codes, and distance bits to reference repeated sequences.
The example shows how literal characters and copy commands are encoded to reduce data size from 24 to 16 bytes.
Decoding DEFLATE manually is complex due to bit-level encoding and the need to interpret various codes and commands.
